A medical researcher wishes to try three different techniques to lower the blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subject's blood pressure is recorded
| group1 | group 2 | group 3 | |
| 13 | 8 | 6 | |
| 12 | 6 | 4 | |
| 11 | 4 | 3 | |
| 15 | 7 | 5 | |
| 9 | 5 | 4 | |
| 8 | 0 | 2 | |
| mean | 11.33 | 5 | 4 |
| sd | 2.58 | 2.83 | 1.41 |
1) Identify the null hypothesis. 2) Identify the alternative hypothesis. 3) Determine the value of the F test statistic. 4) Identify the P-value. 5) State a conclusion about the null hypothesis. 6) State a final conclusion that addresses the original claim. 7. Write the result in APA format

A medical researcher wishes to try three different techniques to
lower blood pressure of patients with high blood pressure. The
subjects are randomly selected and assigned to one of three groups.
Group 1 is given medication, Group 2 is given an exercise program,
and Group 3 is assigned a diet program. At the end of six weeks,
each subject's blood pressure is recorded, with data as shown
below.
The reasearcher will use this data to test the claim that there...

A researcher wishes to determine whether the blood pressure of
vegetarians is, on average, lower than the blood pressure of
nonvegetarians. Independent simple random samples of 85 vegetarians
and 75 nonvegetarians yielded the following sample statistics for
systolic blood pressure:
Vegetarians
n1= 85
= 124.1 mmHg
s1 = 38.7 mmHg
Nonvegetarians
n2 = 75
= 138.7 mmHg
s2 = 39.2 mmHg
Use a significance level of 0.01 and P-value method to test the
claim that the mean systolic blood pressure...

3. Three different treatments for hypertension (high blood
pressure) are being tested. A medical researcher takes volunteers
and randomly assigns them into groups taking treatment A, B, and C.
The reduction in blood pressure is measured for each patient with
the following results:
> d patient treatment reduction 1 1 A 7.0 2 2 A 7.9 3 3 A 5.0
4 4 A 8.3 5 5 A 3.3 6 6 A 2.8 4 7 7 A 3.9 8 8 A...

A medical researcher is investigating the effect of drinking
coffee on systolic blood pressure. The researcher assumes the
average systolic blood pressure is 120 mmHg. For a random sample of
200 patients, the researcher takes two measurements of systolic
blood pressure. The first systolic blood pressure measurement is
taken during a week when the patients drink no coffee, and the
second systolic blood pressure measurement is taken during a week
when the patients drink at least two cups of coffee....

A medical researcher is studying the effects of a drug on blood
pressure. Subjects in the study have their blood pressure taken at
the beginning of the study. After being on the medication for 4
weeks, their blood pressure is taken again. The change in blood
pressure is recorded and used in doing the hypothesis test. Change:
Final Blood Pressure - Initial Blood Pressure The researcher wants
to know if there is evidence that the drug reduces blood pressure.
At...
